switch (e.keyCode) {
case 38: // up
var selected = grid.datagrid('getSelected');
if (selected) {
var index = grid.datagrid('getRowIndex', selected);
grid.datagrid('selectRow', index - 1);
} else {
var rows = grid.datagrid('getRows');
grid.datagrid('selectRow', rows.length - 1);
}
break;
case 40: // down
var selected = grid.datagrid('getSelected');
if (selected) {
var index = grid.datagrid('getRowIndex', selected);
grid.datagrid('selectRow', index + 1);
